Abstract

Um preditor de vetor de movimento temporal é incluível, juntamente com um ou mais preditores de vetor de movimento espacial, em um conjunto de preditores de vetor de movimento para um bloco a codificar de um quadro atual. Um método de determinar o preditor de vetor de movimento temporal compreende selecionar como o preditor temporal um vetor de movimento entre vetores de movimento em um bloco de referência de um quadro de referência diferente do quadro atual. O bloco de referência é um bloco do quadro de referência colocado com o bloco a codificar ou um bloco do quadro de referência vizinho ao bloco colocado. A seleção se baseia em um critério de diversidade para obter diversidade entre os preditores do conjunto. Isso pode reduzir as exigências de memória de vetor de movimento com nenhuma penalidade ou nenhuma penalidade significativa de eficiência de codificação adicional. Alternativamente, mesmo se a memória de vetor de movimento não for reduzida em tamanho, aperfeiçoamentos em eficiência de codificação podem ser obtidas.A temporal motion vector predictor is includeable, along with one or more spatial motion vector predictors, in a set of motion vector predictors for a block to be coded from a current frame. A method of determining the temporal motion vector predictor comprises selecting as the temporal predictor a motion vector among motion vectors in a reference block of a reference frame different from the current frame. The reference block is a reference frame block placed with the block to be coded or a reference frame block adjacent to the placed block. The selection is based on a diversity criterion to obtain diversity among the predictors in the set. This can reduce motion vector memory requirements with no or no significant additional coding efficiency penalty. Alternatively, even if the motion vector memory is not reduced in size, improvements in coding efficiency can be achieved.
